Developing A Robust Teaching Portfolio As A Doctoral Student In A Research-Intensive Engineering Program, Anahid A. Behrouzi

Architectural Engineering

Successful faculty applications to teaching/undergraduate institutions can be difficult for doctoral students transitioning directly from a research-intensive engineering program. Oftentimes, these prospective faculty members have limited opportunities to engage in engineering education research, to serve as a primary instructor for a lecture course, or to receive adequate mentoring to prepare them for the environment of a teaching/undergraduate institution.

This paper will highlight the lessons learned by a new faculty member at a top-ranked undergraduate institution (and recent doctoral candidate at a R1 research institution) about how students can build a comprehensive teaching portfolio outside of the traditional coursework and research …

The overflow port is configured to separate gas within the vessel from the external environment. The system also includes an overflow conduit having an end within the overflow port so that when gas pressure within the vessel increases, liquid is received by the over flow conduit. Another system includes a tank defining an air space for receiving …

Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband

Architectural Engineering

Stochastic Subspace Identification is a field of applied mathematics that takes collected experimental time-history data and gives out information about the system that produced the data. SSI is typically used in control analysis but here we apply the methods to the modal analysis of structures. This senior project didn’t involve theory - instead much of the work was in research behind how Subspace Identification works, implementing the algorithm in MATLAB, and applying the program to shake table data to validate the program. In other words, building the framework to make SSI a usable tool and practical learning experience for other …

Mano De La Amistad: A Thin Shell Concrete Structure Designed For The People Of Havana, Cuba, Peter Aster, Marta Blachowicz-Scott, Aaron Cook, Alex Erler, Elizabeth Townsend, Ger Yang

Architectural Engineering

In designing a thin shell structure to cover the performance space on Tribuna Anti Imperialista Jose Marti, in Havana, Cuba, we developed a heavily symbolic concept and further abstracted it to reach our design. Basing the concept on the quote to the right by Obama about US and Cuba relations, we wanted our design to be representative of a hand that works to adjoin the plaza to the US Embassy which is directly west of the site. The “wrist” portion adds an asymmetric element, while the fingers provide a backdrop to the performers as well as a view through to …

The Ginkgo Shell, Mark Luzi, Karla Santos, Josh Cannon, Erika Davis, Nora Villanueva

Architectural Engineering

The overall concept for this outdoor concrete shell structure, located in Furstliche Park in Inzigkofen, Germany, is derived from an abstracted ginkgo leaf. Drawing on inspiration from a poem about the two parts of the ginkgo leaf becoming one, we took the approach of combining both the natural and built environment into one cohesive piece. To connect the two, it was imperative that we place the shell on the site as to have the smallest impact. With a small portion of the overall site used, the unoccupied space further enhances the natural environment. Creating a literal design connection between the …

Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

The first aspect of this project …

Speculations On A City For Mars, Edouard Terzis

School of Architecture - Theses

This thesis proposes the reinterpretation of architectural forms as the index of the constitution of the idea of the city. “Speculations on a City on Mars” is paradoxical in a sense as it superposes both the managerial representation of a city, that is Zoning, along with the speculative aspect of an extra-terrestrial city.

Modular House Revival, Kevin Chiang, Spencer Dilley, Sarah Dowthwaite, Trevor Houghton, Ryan Lefebvre, Michele Leung, Cameron Lober, Chris Martinez, Katie Mayer

Architectural Engineering

The Modular House, located in Poly Canyon, has seen extensive damage since the last caretaker left nearly ten years ago. To prevent further damage and improve the safety and appeal of the structure, we are proposing a renovation of the existing building that removes the existing cladding and partitions. By the end of Spring Quarter 2017, the Modular House will have a guardrail system replacing the wood paneling on the walls and a new steel composite deck to replace the current flooring system. The structural steel framing system will remain as is.

Design And Simulation A Novel Three-Phase, Five-Level Inverter Topology, Fares Al Juheshi

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

There is a high integration of renewable energy sources in modern building electrical systems. The main components of these new systems are power electronics switches that inherit their foundations from signal amplifier technologies and then developed to drive high powers. Nowadays, the static converter can connect systems with different electrical characteristics. For instance, choppers connect two DC systems with different voltage levels, whereas inverters transform power from DC to AC with variable amplitude and frequency. Since multilevel inverters offer a better quality of the output waveforms than standard inverters, a novel three-phase, five-level inverter topology is proposed. The goal of …

Exploring The Correlation Between Occupied And Unoccupied Noise Levels In K–12 Classrooms, Laura Caroline Brill

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Students learn in occupied spaces, yet acoustical standards specify recommendations for unoccupied levels. While some studies have quantified the relationship between occupied and background noise levels in classrooms, their definitions of background noise level were often inconsistent with those recommended by the standards. The research presented in this thesis examines the relationship between occupied and unoccupied levels in 110 classrooms in two Midwestern school districts. Acoustic levels were logged for a total of six days in each classroom. Occupied and unoccupied levels were parsed from the logged data using k-means clustering, an unsupervised statistical learning technique. The results from this …

Dermal Uptake Of Phthalates From Clothing: Comparison Of Model To Human Participant Results, Glenn Morrison, C. J. Weschler, G. Bekö

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this research, we extend a model of transdermal uptake of phthalates to include a layer of clothing. When compared with experimental results, this model better estimates dermal uptake of diethyl phthalate and di-n-butyl phthalate (DnBP) than a previous model. The model predictions are consistent with the observation that previously exposed clothing can increase dermal uptake over that observed in bare-skin participants for the same exposure air concentrations. The model predicts that dermal uptake from clothing of DnBP is a substantial fraction of total uptake from all sources of exposure. For compounds that have high dermal permeability coefficients, dermal uptake …

Uncovering The Mystery Of Machu Picchu, Barbara Cardona

Butler Journal of Undergraduate Research

If mysteries were ranked, Machu Picchu would be on the top of the list. This Incan site, destination for millions of tourists, archaeologists and researchers each year, is one of the biggest enigmas of Incan culture. Its mesmerizing view has prompted hundreds of unanswered questions about this civilization. Incan culture revolved around cities, built without reference to the world beyond. Although the Incas were incredible architects and inventors, they lack written records, shrouding their culture in mystery for many years. While research has illuminated some facets of Incan culture, a significant question still remains: what purpose did Machu Picchu play …

Experimental And Numerical Investigation Of Flexural Concrete Wall Design Details, Anahid A. Behrouzi, T. Welt, Dawn Lehman, Laura Lowes, J. Lafave, Daniel Kuchma

Architectural Engineering

Reinforced concrete structural walls are common in mid- to high-rise structures in high seismic regions, and are expected to have good strength and ductility characteristics if designed in accordance with ACI 318-14. However, experimental and analytical investigations of reinforced concrete structural walls and isolated boundary element prisms indicate that the existing design provisions may be insufficient to provide ductile, flexure-dominated response under cyclic loading. Walls designed with an ACI compliant boundary element length are susceptible to shear-compression failures below the maximum ACI allowable shear stress of 10Acv√fc’. Also of concern is the frequent use of thinner walls in modern design; …

Wall Panel Optimization For Refugee Shelters In Germany: An Ahp Study, Zhu Jiadong

Masters Theses & Specialist Projects

The German government is experiencing difficulties housing and assimilating Syrian refugees in its borders. Erecting temporary shelters on location is one way to deal with the current crises. This thesis attempts to use Analytic Hierarchy Process (AHP) to determine the optimum combination of materials and construction methods to be used in the shelter’s walls in order to improve the living conditions of the refugees and to ensure that the cost is acceptable to the German government. This thesis compares six existing wall panel products from China, which have the lowest cost on the worldwide market. The R-value, strength, price, weight, …

How Tonality And Loudness Of Noise Relate To Annoyance And Task Performance” Noise Control Eng. J. 65(2), 71-82., Joonhee Lee, Jennifer M. Francis, Lily M. Wang

Durham School of Architectural Engineering and Construction: Faculty Publications

Audible tones in noise generated by building mechanical equipment can be a leading cause of complaints from occupants. A number of metrics have been developed to quantify prominence of a tone, but previous work has shown that the impact of a certain tonality appears to vary with the level of the broadband noise signal. More work on how tonal signals of varying tonality, tone frequency and broadband noise levels relate to annoyance and task performance is needed. This paper investigates such relationships between current noise metrics, annoyance and task performance under assorted tonal noise conditions through subjective testing. Participants rated …

Numerical Simulations Of Intrusive Gravity Currents Interacting With A Bottom-Mounted Obstacle In A Continuously Stratified Ambient, Jian Zhou, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, the flow dynamics of intrusive gravity currents past a bottom-mounted obstacle were investigated using highly resolved numerical simulations. The propagation dynamics of a classic intrusive gravity current was first simulated in order to validate the numerical model with previous laboratory experiments. A bottom-mounted obstacle with a varying non-dimensional height of D~ = D/ H, where D is the obstacle height and H is the total flow depth, was then added to the problem in order to study the downstream flow pattern of the intrusive gravity current. For short obstacles, the intrusion re-established itself downstream without much distortion. …

Lateral Strength And Ductile Behavior Of A Mortise-Tenon Connected Timber Frame, Alexandros Kouromenos

Master's Theses

The primary goals of this project were to examine the amount of lateral force resisted by a single-bay mortise-tenon connected timber moment frame, and to introduce ductile behavior into the mortise-tenon connections by adding a steel sleeve around a traditional wood peg. This research aimed to provide proof that traditional timber frames are capable of ductile racking while reliably complying with ASCE 7-10 building code drift speci! cations, implying an increase in the ASCE 7-10 ductility factor (R) for wood frames when used as lateral force resisting elements. A secondary goal was to promote traditional heavy timber framing as a …
